Oil-Flo™ Safety Solvent Cleaner is a specialized product for removing organic stains such as asphalt, tar, coal, grease and oil. Oil-Flo is biodegradable, water soluble and contains no harmful ingredients or chlorinated fluorocarbons. Oil-Flo bonds to the petrochemical, whatever it may be, and then bonds to the oxygen molecules present in water. This two-step process allows a final rinse with plain water that leaves no residue behind. Neutral pH means Oil-Flo won’t harm the surface, only dissolve the stain. Oil-Flo is our most aggressive cleaner.
